germany – What is the weather like in the Black Forest at the end of March?

I have 5 days of annual leave that I need to use by the end of March, and I’d like to do some hiking in the southern Black Forest in Germany, staying in hostels/hotels.

What will the weather be like at this time of year in the Black Forest? Will it still be wintery (e.g., sparse vegetation, maybe some snow), or starting to look like spring (green, no snow)?

Or am I better off just leaving it for later in the year?
